摘 要：Titanium-supported nanoporous palladium catalyst（Pd/Ti） was prepared by a hydrothermal method using PdCl2 as a precursor,ethylenediamine tetraacetic acid（EDTA） as a ligand,and formaldehyde as a reduction agent.Complex Pd-EDTA2-is favorable for the formation of Pd particles with nanoscale sizes.The electroactivity of the Pd/Ti catalyst towards the electroreduction of hydrogen peroxide in 1 mol/L NaOH solution was evaluated by voltammetric techniques.Both linear scan voltammetric and chronoamperometric data present significantly large steady-state reduction current density of the hydrogen peroxide electroreduction on the prepared Pd/Ti catalyst.The results show that the prepared Pd/Ti catalyst is an effective electrocatalyst for the electroreduction of hydrogen peroxide in alkaline media.
